Find the hours your audience is online.
Pick an audience timezone and niche, and we render a 168 hour heatmap of the posting windows where engagement velocity lands highest. Built on our campaign data across thirteen target markets and six niches. The top three windows are surfaced above the heatmap.
For Tech / SaaS targeting Eastern (US), aim to post at the red hours above and avoid the faded ones. Schedule tweets ahead if those windows fall outside your own waking hours. If you are pairing with a paid engagement push, drop the Spark Suite within 15 minutes of the tweet posting.
How the heatmap is built
We clustered engagement data across hundreds of thousands of tweets from our customer campaigns since 2022 by niche and audience timezone. Each niche has a peak hour profile in the local audience timezone, and each day of week has a multiplier derived from actual engagement variance. The heatmap combines both into a score per hour per day.
Why the peaks differ by niche
Tech and B2B audiences engage during working hours with a late evening secondary peak. Finance and crypto audiences peak at market hours and extend into late night because crypto trades 24/7. Culture and creator niches concentrate on evenings and weekends. D2C and consumer niches peak around meal times when people browse phones.
Should I actually post at exactly those minutes?
Aim for the hour. Posting at 2:00 PM versus 2:23 PM versus 2:47 PM changes engagement velocity by less than 5 percent in our data. The hour signal is what matters because that is when people are open and scrolling.
What if my timezone is not in the list?
Pick the closest listed timezone. The heatmap clusters audience behavior by regional pattern rather than absolute offset, so Central European behavior is close enough to Eastern European behavior that the DACH profile is usable for Turkey or Greece. Gulf audiences follow a distinct pattern, which is why UAE is separately listed.
